Problems solved by technology

The existing in-situ treatment technology is mainly to add chemical agents and sediment modifiers to the sediment. This method has a significant effect on improving sediment pollution, but excessive use of chemical agents will inevitably cause secondary pollution to the river.

Abstract

The invention discloses a system for remediating bottom mud in a black and odorous water body based on the electrodynamic principles. The system comprises a positive electrode module, a negative electrode module and a power supply module, wherein the positive electrode module and the negative electrode module are inserted into bottom mud in parallel; the positive electrode module comprises a positive component, a positive filling component and a positive transmission component, the positive component and the positive filling component are both arranged in the positive transmission component, and the positive component is completely wrapped by the positive filling component; the negative electrode module comprises a negative component, a negative filling component and a negative transmission component, the negative component and the negative filling component are both arranged in the negative transmission component, and the negative component is completely wrapped by the negative filling component; and a positive electrode of the power module is connected to the positive component and a negative electrode of the power module is connected to the negative component. According to the system, bottom mud acidification and sediment generation can be reduced, and rising of bottom mud temperature is inhibited; and power consumed in the process of bottom mud purification is reduced, andpollutant removal efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of bottom mud treatment, and in particular relates to a black and odorous water bottom mud restoration system based on the principle of electrokinetics. Background technique [0002] The generation of black and odorous water is caused by the large discharge of industrial wastewater, domestic sewage and farmland catchment water, and the continuous increase of organic carbon pollutants, organic nitrogen pollutants and phosphorus-containing compounds in rivers. In the river channel, the bottom mud is a "sedimentary reservoir" for absorbing and decomposing organic matter, and it is also a "source" for organic pollutants and nutrients in the overlying water. When there is too much sediment in the river channel, a large amount of organic matter in the sediment will consume a large amount of oxygen through microbial oxidation and classification, which will exhaust the oxygen in the lower layer of the river channel,...
